SENSOR OF TURNS OF THE CRANKED SHAFT
Removal
PERFORMANCE ORDER |
1. Remove a weight wire from the accumulator. |
2. Disconnect the electric socket of the sensor of a cranked shaft which is located in a motor compartment behind the accumulator. |
3. The sensor of a cranked shaft is established on an interfaced surface between the block of cylinders and a coupling case over a starter. Unscrew a bolt and remove the sensor of a cranked shaft from a coupling case. Remove laying. |

ELECTROMAGNETIC EXECUTIVE MECHANISM
Removal
Side view of a back part of the fuel pump of a high pressure
|
A–electromagnetic executive ELR mechanism;
B–electromagnetic executive ARA mechanism |
PERFORMANCE ORDER |
1. The electromagnetic executive ELR mechanism is screwed by bolts on a back part of the fuel pump of a high pressure. On cars with electronic control by turns of idling of ELR and system of an anti-detonation of ARA the electromagnetic executive ELR mechanism is the top block from two blocks located in a back part of the fuel pump. |
2. Remove a weight wire from the accumulator. |
3. On models without a turbo-supercharging remove the air filter. |
4. Disconnect the electric socket from the electromagnetic executive mechanism. |
5. Unscrew two bolts and remove the case of the electromagnetic executive mechanism from a back part of the fuel pump. |
6. Remove a sealing ring, laying and an intermediate plate. |
